and novel strategies for the synthesis of thienopyrimidines starting from 2-amino-3-carboethoxy-4,5,6,7-tetrahydrobenzo[b]thiophene has been developed. The regioselectivity of these synthetic strategies was investigated using density functional theory computation and spectroscopic analysis. In addition, the chemical structures of the new thienopyrimidines and their reaction mechanisms, as well as the
摘要 噻吩并嘧啶衍生物在各种药物和生物医学领域是众所周知的。在这项工作中,开发了一系列以 2-amino-3-carboethoxy-4,5,6,7-四氢苯并 [b] 噻吩为原料合成噻吩并嘧啶的有效且新颖的策略。使用密度泛函理论计算和光谱分析研究了这些合成策略的区域选择性。此外,还研究了新型噻吩并嘧啶的化学结构及其反应机理,以及所选化合物的生物活性。
